Mercury toxicity; behavioral changes and recovery in a freshwater teleost Heteropneustes fossilis (Bloch)
Journal Title: Bioscience Discovery - Year 2017, Vol 8, Issue 1
Abstract
Present study was aimed to observe the behavioral changes due to Hg (0.1mg/l) toxicity in the freshwater catfish Heteropneustes fossilis (Bloch). The fishes exhibited erratic swimming, thick mucus secretion over body surface, skin soars and jerky movements. Fishes tried to leap out of aquarium during experiments. It was further observed that these behavioral changes were suppressed when fishes were simultaneously fed with herbal compound. The recovery experiments confirmed that the behavioral changes due to Hg toxicity were reduced when fed with the herbal compound, indicating its protective effects against Hg toxicity.
